With the MTV Movie Awards and Coachella both happening this weekend, it was time for celebrities! Just about everyone was at the music festival, and we've rounded up the best photos, videos, news, and more. Behold:

First up, Beyonce surprised the crowd when she joined her sister Solange onstage during her set! The two danced and performed Solange's "Losing You" together.

Queen Bey also posted a ton of pics of her time at Coachella on her Tumblr. Go [check them out](http://iam.beyonce.com/tagged/my_life), but I suggest only when you know you have plenty of free time—it's a rabbit hole of gorgeousness.
Not as exciting as, um, BEYONCE, but [Justin Bieber](/about/justin-bieber) also gave a surprise performance when he joined Chance the Rapper onstage. Video below, but careful as there's some language.

And those weren't the only surprise performances: The one-and-only Gwen Stefani stopped by Pharrell's set to sing "Hollaback Girl." Oh, how I wish I could have seen that in person.

And although no surprise guests dropped by her set, Lana Del Rey did premiere her new single "West Coast." Listen below!

But perhaps the most talked-about moment from Coachella this weekend was Leonardo DiCaprio's awesome dance moves. Just watch the video because no words can describe:

Other celebrities in attendance included [Selena Gomez](/about/selena-gomez), who spent the weekend partying it up with [Kendall](/about/kendall-jenner) and[ Kylie Jenner](/about/kylie-jenner).
